TO ALL WHOM 1T MAY CONCERN:

Be it known that I, J. M. WILLBUR, of Cleveland, county of Cuyahoga, in the State of Ohio, have invented a new and improved Automatic Cylinder Rotary Printing-Press; and I do hereby declare that the following is a full and exact description thereof, reference being had to the 'accompanying drawings, and to the 'letters of reference markedthereon.

Figurel is a plan view.

Figure 2 is an end elevation.

Figure 3 is a side elevation.

FigureA isa sectional view of the ink-holder.

Figure 5 is a detached view of'a stereotype-cylinder, with changeable types for changing dates, as in postoiiice and revenue stamps.

Figure 6 is a section of endless belt and ink-holder, taken on line z :n of g. 1.

Figure 7'is a longitudinal cross-sectionof the governor, levers, and plate, showing the mode of operation in the dotted lines.

Figure 8 is a cross-section of the cylinder D, showing the mode ofl changing dates. y

The nature of this invention relates to the construction of a small printing machine which may be' selfoperating, it having a spring and clock-work movement attached, which may be wound up and employed to run said machine. This machine has removable cylindrical stereotype plates, which enable itto be used for a variety of small job work, such as cards, circulars, envelopes, bill-heads, druggists labels, and so forth. The cylindrical stereotype plates may also have changeable types for changing dates, as in post-oilice or revenue stam'ps-s which enable it to be used for post-ofiice letter-stamping and cancelling.

The following is a description of the machine, and its manner of operation.

.A is a frame, which supports all the mechanism. B is a case or chamber attached to one side of tho frame,

which contains a coiled spring, employed as the motive power for running the machine, and is secured to the shaft I b; and upon this shaft is placed the driving-wheel C, which connects with the small wheel c, and runs the other machinery through the gear-wheels d, e, and f. D is a cylindrical stereotype plate, which is first` cast iiat and afterwards bent and formed into a cylinder, and maybe placed upon the roller D2, and being removable, gives opportunity for doing a variety of printing. The circumference may have any reading matter upon it. The said type-cylindermay also be arranged with changeable type, (sec g. 5,) for changing dates for stamping and cancelling purposes. Underneath the cylinder D there is au adjustable impressioncylinder, E, there being adjustable journal-boxes v v and set-screws s s attached to the frame A for that purpose. F is an inkholder or reservoir, and consists of two cylinders, (see iig. 4,) one fitted closely inside of the other, each being perforated alike. In' one end ofthe outside cylinder there is a set-screw, g, by which the inside cylinder may be made to slide leugthways, and cause the openings in the two cylinders to be opposite, and open through or closed, as may be desired, to regulate the supply of ink. Underneath this ink-cylinder is an endless belt, H, of cloth, covered with rubber or other suitable material, and which is placed upon the two rollers 7i h. This-belt is used as an ink-distributing surface, und between it and the type-cylinder D is placed an inking-roller, J, for inking the type on the cylinder D. K isa device for regulatingthe motionof the machine, and consists of two balls, k, attached to the levers ZZ, which are pivotcd to the cross-bar m. Between the levers llthere is a spiral spring, 1t, attached to the set-screws o o in the levers, by which the levers may be adjusted to control the spread of the balls when revolving. This device is placed uponthc shaft p, which derives its motion from the pinion q', turned by the wheel w, which is connected by the shaft and pinion x with the main driving-wheel C. It will be seen that when revolving, the balls It lc, by the centrifugal force, are inclined to spread, by which the levers ZZ are made to-bear against the plate y, (as shown in g. 7 in dotted out lines,) which causes suiiicient friction to regulate the motion of the machinery, as the power of the coiled spring is greater when coiled up than when nearly uncoilqd. T -is a brake upon the side of the frame, having a thumb-screw, t, which may be used to bear against the wheel d, and stop the machine whenever desired.

This machine is very useful for printing small job work, as the stereotype cylinders maybe readily removed and others placed instead vby having the roller arranged so as to be taken out; and by having changeable types for changing dates, may be useful' for cancelling and stamping letters and papers in post oices.

The journals D2 of the roller D'may be placed in boxes set in springs, so as to yield to the inequalities that may arise while stamping letters or papers of unequal thickness.

By the use of this machine for post-oce stam-ping und cancelling, purposes there would be a great saving of labor, and the work would be much more perfectly done, as the impressions would be clean and perfect, as the ink is well distributed and the plates are well inked. l

Having thus described my invention, what I desire to secure by Letters Patent, is- 4 1. I clnim the governor-device 7c, constructed in the manner described, to operate as and for the purpose set forlth.

2. I claim the cylindrical ink-holder F, constructed in the manner described, to operate in the manner shown, as and for the purpose set forth. v v

3. I claim the driving mechanism, when regulated by the governor-device Ic, constructed as described, and combined with n printing machine, substantially as and-for the purpose set forth.

4. The cylindrical removable stereotype D, provided with the changeable dating-type X. and permanent inscription W, when used in combination with the automatic printing machine described, as and for the purpose set forth.

J. M. WILLBUR.
